13N24 - ESAB 13N24 TIG Collet 1/8" (3.2mm) for 9/20/25 Torches - 5 Pack

Technical Overview of the ESAB 13N24 Collet

The ESAB 13N24 Collet is a precision-engineered consumable component designed for Gas Tungsten Arc Welding (GTAW) applications. Specifically manufactured to accommodate 1/8-inch (3.2mm) tungsten electrodes, this collet serves as the critical electrical and mechanical interface within the TIG torch assembly. It is constructed from a high-grade copper alloy, selected for its exceptional electrical conductivity and thermal dissipation properties. These material characteristics are essential for minimizing resistive heating at the contact point, thereby ensuring consistent current transfer to the electrode and maintaining arc stability during operation.

This component conforms to the industry-standard 13N24 specification, ensuring broad compatibility with 9, 20, and 25 series TIG torches. This includes popular models such as the air-cooled WP-9 and the water-cooled WP-20 and WP-25. The collet operates via a radial compression mechanism; as the torch's back cap is tightened, the collet is driven into the tapered seat of the collet body. This action compresses the split-sleeve design around the tungsten electrode, securing it in a concentric position relative to the gas lens or nozzle. Proper concentricity is vital for directing the shielding gas flow and preventing arc wander, particularly in precision welding tasks.

Thermal cycling is a significant factor in collet performance. The ESAB 13N24 is designed to withstand the expansion and contraction cycles inherent in welding without permanent deformation, provided it is used within its rated amperage limits. However, over extended periods of use, mechanical fatigue and thermal stress can compromise the collet's gripping ability. This pack of five units allows for proactive maintenance schedules, ensuring that operators can replace worn components immediately to prevent quality degradation. The 1/8-inch size is typically utilized for medium-to-heavy amperage applications, suitable for welding thicker gauges of aluminum, stainless steel, and mild steel.
